Growth and nitrogen fixation by Trifolium subterraneum plants at 15 and 10 o C root temperatures is much less in test tubes plugged with cotton wool than in open pots of sand. Removing the ethylene produced by plants growing in cotton wool plugged flasks by adsorption onto activated charcoal, or by aerating with sterile air, increased nitrogenase activity and growth over the first 25 days, to levels approaching that of plants grown in open pots of sand.
